I am a newbie studying ABB robots. I am studying components in the IRC5. I know K42 and K43 are motor-on contactors. What are K1 & K2? I am quoting the following directly from a ABB manual. "The motor contactors K1 K42and K2 K43 in the controllerdrive module can operate with external equipment if external relays are used." Thank you.

Although I'm not to familiar with the subject I was able to find the information below. According to the manual K1 and K2 are signals that are part of safety I/O. The signals are checking the state of contactors, DRV1K1 and DRV1K2. I'm not sure if this is what you were looking for but hope it may help you out.
DRV1K1-Read back of contactor
K1, chain 1
